Whiplash: a biochemical study of muscle injury

Abstract
Outcome following whiplash injury of the cervical spine is variable, and the pathology of those with prolonged symptoms is uncertain. We undertook a prospective study in 25 patients to identify whether those with prolonged symptoms following whiplash injury exhibit a rise in serum creatine kinase consistent with significant muscle damage at the time of injury. Transient rise in creatine kinase level was seen in only 2 of 25 patients, neither of whom complained of prolonged symptoms. Of the 8 patients who developed chronic symptoms following whiplash injury, none demonstrated a serum creatine kinase rise. Prolonged symptoms following whiplash injury cannot be explained by biochemically measurable muscle damage.
